Synopsis:

#include <pthread.h>

A pointer to the pthread_spinlock_t object that you want to destroy.

Library:

Description:

The pthread_spin_destroy() function destroys the thread spinlock spinner, releasing its resources.

Once you've destroyed the spinlock, don't use it again until you've reinitialized it by calling pthread_spin_init().

Calling pthread_spin_destroy() gives undefined results when a thread has spinner locked or when spinner isn't initialized.

Returns:

EOK

Success.

EBUSY

The thread spinlock spinner is in use by another thread and can't be destroyed.

EINVAL

Invalid pthread_spinlock_t object spinner.
